摘要： An image display apparatus for displaying images based on signals of an input image is provided. A backlight emits light. A liquid crystal panel modulates light emitted from the backlight. A emission intensity calculating unit calculates an emission intensity of the backlight such that a center value of a lightness range displayable on the panel defined depending on the emission intensity of the backlight substantially agrees with a center value between maximum and minimum values of lightness of each signal of the input image. A backlight controlling unit controls light emission of the backlight such that the light is emitted with the emission intensity. A signal correcting unit corrects each signal of the input image in accordance with the emission intensity. A liquid crystal controlling unit controls modulation of the liquid crystal panel based upon the corrected signals.
